Sims 1 isometric coordinates, some questions..

[francot514]

Hi, im doing research for sims 1 houses, trying to understand floor arrays and figure out how the isometric coordinates system work ingame, i need some help, based on the image i got, can conclude this, maybe im wrong...

-How does isometric coordinates calculate the x,y cartesian and the real isometric x, y??
-The isometric view contains extra coordinates variables??

Real xy is from 0 north-west to positive south-east. Each tile has 16x16 subtiles. Objects positions are most likely stored in 16th units.

I'm not sure what your image means.

My image is the conclusion i got from reading sims 1 house floor arrays...

Each tile is 512x512, increases by 512, but in some values seems to increase by a quantity 32000 to 64000??
Can you tell me how to calculate isometric having x,y coords??
